To all fwhomiaL may concern:

Be it known that I, JoHN J; S'rooK, a citizen' of the United States, and a resident ,of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Bumper, of which the following isa full, clear, and exact description.

. My invention relates to a bumper and aims to provide a device of this character primarily adapted for use in connection with an amusement vehicle, such as has been illustrated in my prior Patent N o. 1,339,299, dated May 4, 1920, it being understood, -however, that the present invention is not necessarily limited to this adaptation.

It is a` well understood fact in connectior with pleasure ridesin which a number of vehicles are utilized, which vehicles engageeach other, or relativelyfixed surfaces, that it is necessary to provide cushioning means which will prevent the transmission of too great a shock to the parts of the vehicle and the occupants therein when this engagement is eected. Vifith this in mind a number of bumpers have been placed upon the market with a view of providing a means which would serve to cushion the shocks incident to the engagement of a vehicle with a second vehicle or with relatively fixed surfaces. These bumpers for the most part have often a number of objections, among which will be notedthe fact that they were relatively cumbersome and consequently added material weight to the vehicle that they did not eifectually cushion the shocks and also that the cushioning properties were quickly lost after the bumper has been subjected to usage for a certain length of time.

Thus my present inventions aims to provide a bumper which is, as aforestated, primarily adapted for use' in connection with vehicles of a pleasure ride, but is not necessarily limited to use. in this connection, and by means of which, primarily, an element will be presented which may readily be manufactured and subsequently associated with a vehicle and which will further be capable of withstanding a greatv amount ot' usage and which will at all times eEectually cushion shocks. y

l/Vith these and further objects in mind reference is had to the attached sheet of drawings as illustrating one practical em- Applcation iled .August 3, 1921. Serial No. 489,526..

Specification of Letters Patent. Patented June 13 192,2.

bodimen't ofvmy invention, `and it will be seen from these drawings that l e f Figure 1 is a side elevation of a pleasure vehicle and showing my improved type of bumper associated therewith;

Figure 2 is a fragmentary side elevation of the ends of said bumper element;

`Figure 3 is a sectional side yView taken along the line `3-3 and in the/,direction of the arrows indicated in Figure 2; and Figure 4 is ra transverse sectional View of the device as shown in Figures 2 ,and 3.

lReferring now more particularly to Figure l, it will be seen that reference numeral 5 indicates the body oit-a pleasure vehicle, which in the embodiment illustrated, is annular ortub-shaped, the outermost portion 6 of said vehicle being provided with a groove (clearly shown in Figure 4f), within which the body oit the bumper lies.

It will be seen in Figure that the body of the bumper preferably includes an eX- terior tube/shaped casing "if which is retained in an iniated condition by means of an inner tube 8 as in the case of a pneumatic tire. However, the body of each of these tubes is cut transversely to provide a pair oiiend portions so that the device may readily be applied to the groove formed in the body of the vehicle.

To now provide means which will serve to join theI ends of the tubes together in such a manner as to guard against fluid leakage, and which will further serve to provide attaching means anchoring the tubes to the body of the vehicle, it will be noted upon reference being had to Figure 3, that a sleeve 9 is introduced into the ends of the inner tube 8, and with a View of providing a fluid-tight seal at these points, it will be noted that the sleeve is formed with a series of annular ridges 10 upon its eXterior face so that the inner tube 8, incident to its elasticity, will lie flush against the exterior face ot the sleeve 9, and incident to the engagement with the ridges l0, will be prevented 'from becomingaccidentally detached from this member, as well as viding means insuring a Huid-tight seal.

It will further be noted in this connection that a conventional tire valve ll may be associated with the sleeve 9, and by this means fluid maT7 be introduced into the inner tube 8. Also to clamp the casing 7 prothe vehicle a pair of collar-shaped members l2 is employed. 'Each ofthese latter members includes the provision of a split band which is circumferentially adjustable by the utilizationofbolts and nutsI 13 provided for.

thispurpose, VAlso each of the coll'arslQ carries a-stud 13 which is adapted to eX- tend through an opening 11i forming the baseV of the groove arranged within the body of the vehicle. l

Incident to `this construction it Will be understood that by tightening the collars by means of the bolts and nuts 13, that the casing@ may be pressed into intimate contact with the inner tube 8 and these latter elements will be forced into tight engagement with the exterior face of the sleeve'9, thus preventing Aany accidental detachment of the elements one from the other and also further insuring the provision of a leakproof joint. Further by means of the studs 13 cooperating With the openings 14, itwill be ,appreciated that a circumferential shifting of the'bumper with respect to the body of the vehicle will be absolutely precluded,- thus guarding against unnecessary Wear.

. -From .theforegoing itivill be understood that vall of the objects set forth in the preamble of this specificationare .accomplished and it will further beappreciated that numerous modifications of structure might sleeve adapted to be inserted into said end portions, and collars encircling said casing.
